Sortable: How do I change ui.helper when it enters an undroppaple zone?
In a sortable list where a part of a list is unsortable I need to
change the look of the ui.helper to give a response to the user that
the item can not be dropped there.
The options "over" and "out" do not solve the issue. Out is only fired
when the item leaves the list, not when it leaves the droppable zone.
Does anybody have an idea how to do this?
